I just modded them completely with a combo of self-adhesive felt, acoustic foam and cotton. Will give them a listen tomorrow (hope I won’t be disappointed)

Maybe try ebay. I lost my opportunity to get the S500's, they are not selling anymore in amazon from my country, neither amazon usa. Although I don't regret my buy, the GM200 are really a nice jewel and I'm planning on get the Pro's 82.

If you want an even more balanced and natural sound than GM200, Pro 82 v2 is the right decision.
Just make sure you buy it at the store that actually ships v2, and not v1/v0.9.

Listening to them right now. When the fit is right, they have a timbre that is like honey for your ears, yet it’s natural without any grain

Guys I’m wondering, what will happen to the sound if you puncture these holes on the driver (red marked it)?

I have them playing music at deafening volumes since last night, since mine didn’t fully burn in yet (they have 12 hours from a previous session I did last year)

Before I let them burn-in, they were too bright in the highs.

Will playing music at very high volumes burn them in properly? Also, would the highs smooth out a bit once they’re fully burned in?

Playing random music at higher than typical listening volume, will burn it just fine.
The specific effects of burn-in may be different from what I have listed in the first post, due to your mod.

Can the drivers handle all that volume? It’s really loud, like 100 dB

Just set normal listening volume, then add about 20-30%.

Took the S680 out since 3 days and gave them a listen. There’s distortion that wasn’t there before. I used another headphone with the same tracks , and confirmed that distortion isn’t there with that headphone.

It appears the drivers are damaged... How could that be, since the diapghram is made out of cnt material?

Wait, I just read the maximum input power is 1 watt. Does that mean that the driver only start to get damaged at 1 watt?

Did you burn it at 20-30% above listenable volume? It shouldn't cause any damage, not even close.

Yes. Max volume of the player is 31. Listening volume would be 16, above listening volume would be 20. I had it at 26 volume.

I also had 1 ply of toilet paper and charcoal foam on the front side of the driver while burning them in (I find the treble too bright). Would that trap the sound in more, thus causing more damage to the driver, or would it not matter to have 1 ply of toilet paper and charcoal foam on the front while playing at that volume?

If normal listening volume is 16, then 26 is definitely too high.
Having paper/foam would cause some additional volume pressure.
Was the paper/foam touching the driver? That could cause some physical damage.

Is there a remedy to remove the distorting sound caused by the too high volume? Does not using it for a while fix that?

The paper/foam was resting against the front side, there’s a mesh there so it wasn’t phsyically touching the driver, just laying against the mesh.

Looks like it was creating additional pressure over a small area - can be dangerous

Your guess is as good as mine, I guess resting it the only available option.
